use tokio::io::AsyncWriteExt;

#[tokio::main]
async fn main() {
    let mut sf = SpooledTempFile::new(10);

    sf.write_all(b"12345").await.unwrap();
    assert!(!sf.is_rolled());

    sf.write_all(b"6789abc").await.unwrap();
    assert!(sf.is_rolled());

    assert!(std::matches!(
        sf.into_inner().await,
        Ok(SpooledData::OnDisk(_file))
    ));
}
